IMPROVEMENT To all whom it may concern:

Be it known that we, WILLIAM CRAIG, of Brooklyn, in the county of Kingsand State of New York, and ALEXANDER M. LEsLEY, of the city, county, andState of New York, have invented certain new and useful Improvements inGas-Stoves; and we do hereby declare the following to be a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, figures, and letters of reference thereon, making part of thisspecification.

Of the said drawings, Figure 1 is a perspective view of a gas-stoveembodying our invention. Fig. 2 is a yertical sectional view of thesame. Fig. 3 is a horizontal section taken through the line A B, Fig. 2.

Similar letters of reference indicate like parts in all the drawings.

Our invention consists, first, in combining with a gas-stove a steamgenerator or boiler, whereby a current of steam may be generated andthrown in contact with the flame of gas, and thereby insure more perfectcombustion and greater heat.

The second part of our invention consists in combining with a gas-stoveanda steamgenerator a cone for directing the steam to the flame of gas.

The third part of our invention consists in a novel arrangement of partswhereby a current of steam is made to act upon a flame of gas forgenerating steam in the boiler.

To enable others skilled in the art to make and use our invention, wewill describe the construction and operation thereof.

A represents a sheet-metal cylinder, the lower end of which is fitted tothe base B and the upper end to the top (3, and the three parts aresecured together by bolts and nuts. The base B is cast withperforations, and the top 0 open for obtaining a good draft of air.

D is a steam-generator, which is inserted within the cylinder A, and issupported upon the pipes to b, one of which, a, is a pipe for fillingthe boiler with water, while the other, 1), forms the induction-pipe andburner for the E is a cylinder, the lower end of which is open and restsupon the base B, while the other end is covered with a finely-perforatedIN GAs-sTovEs.

plate or sieve, I. On top of this perforated plate or sieve there is asmall circular plate, It, around the circumference of which the gasrises to generate steam in the boiler D.

In the bottom of the cylinder a pipe, d, is inserted, which has a shortelbow, m, through which gas passes to the cylinder by the cock 1', andrises, assisted by the draft of air, through the perforated plate orsieve Z.

To the generator D a tube, a c, is attached, (see Fig. 2,) which passesdown the cylinder A and into the cylinder E, for conveying a current ofsteam, which acts to force the flame of gas upon the under surface ofthe boiler, and greatly facilitates making steam.

In the top plate of the boiler we cut a hole for the passage of aconical tube, e,(see Fig. 2, dotted line's,) which tube is made tight tothe boiler-cap before the cap is screwed to the shell. The bottom ofthis pipe 6 is perforated or cut away, so that water will pass to theinside thereof.

The operation will be as follows: The boiler D is filled with waterthrough the pipe a, the plane of the pipe being lower than the top ofthe boiler to allow sufficient steam -room. The end of the tube 1) isplugged or capped and a row of small holes made just below the plug forthe gas. The gas is then taken through the pipe h, which connects withthe pipes (I and b by means of the pipefand coupling. 9, and the flowisregulated by the cooks z'j. The gas is lighted at the pipe m, andrising up to the boiler heats the water, generates steam, which passesthrough the pipe at 0 into the cylinder E, and forces the flame of gasthrough the perforated plate 70 and against the boiler with a greatlyincreased effect, and steam is holes in the pipe I), the flame rising upthrough the cone 0, assisted by a draft of air up through the cylinderA. The steam, which is generated from water inside the cone 6, risingup, causes the flame of gas to expand, produces more perfect combustionand increased heat, and destroys the disagreeable odor arising from gas.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a gas-stove, of a made rapidly. The gas is thenlighted at the steam generator or boiler, whereby a current I 3. Thecombination and arrangement of the or jet of steam is-generated andthrown up in contact with a flame of gas, thereby insuring more perfectcombustion and greater heat, substantially as described and specified.

2. Combining with a gas-stove constructed with a steam-generator,substantially as described. a cone, 6, or equivalent device, fordirecting the steam to the flame of gas, substantially as described, andfor the purposes specified.

steam-generator D, cone 0, pipes b and d, with their connection, and thecylinder E, con structed and operating substantially as described andspecified.
